How to Install Redis on Amazon Linux

Learn how to install and configure Redis on your Amazon Linux instance with this step-by-step guide.

Redis is an open-source, in-memory data structure store that can be used as a database, cache, and message broker. It is widely used for its high performance, simplicity, and versatility. If you are using Amazon Linux and want to harness the power of Redis, this comprehensive guide will walk you through the step-by-step process of installing and configuring Redis on your Amazon Linux instance.

Introduction to Redis

Redis is an advanced key-value store that provides high performance and can be used as a cache, database, or message broker. It supports various data structures such as strings, hashes, lists, sets, and sorted sets, making it a versatile tool for developers. Its in-memory nature allows for lightning-fast operations, making it suitable for use cases that require low latency and high throughput.


Before we begin, ensure that you have the following:

  • An Amazon Linux instance with root access or administrative privileges.
  • Basic knowledge of Linux commands and the terminal.

Step 1: Update the System

To ensure that your system is up to date, it is recommended to update all the installed packages. Open the terminal and execute the following commands:

sudo yum update -y

This command will update all the installed packages on your Amazon Linux instance.

Step 2: Install Redis

Now that your system is up to date, you can proceed with the installation of Redis. Execute the following command in the terminal:

sudo yum install redis -y

This command will install Redis on your Amazon Linux instance.

Step 3: Configure Redis

Once Redis is installed, you need to configure it to suit your requirements. The configuration file for Redis is located at /etc/redis.conf. Open the file using a text editor of your choice:

sudo nano /etc/redis.conf

In this file, you can modify various settings such as the port, bind address, and memory limits. Make any necessary changes and save the file.

Step 4: Start and Enable Redis

After configuring Redis, you can start the Redis service and enable it to start automatically on system boot. Execute the following commands:

sudo systemctl start redis
sudo systemctl enable redis

These commands will start the Redis service and configure it to start on system boot.

Step 5: Test Redis Installation

To ensure that Redis is installed and running correctly, you can perform a simple test. Open the Redis CLI by executing the following command:


Once the CLI is open, you can test Redis by setting and retrieving a key-value pair. For example:

set mykey "Hello, Redis!"
get mykey

If Redis is functioning properly, you should see the value associated with the key mykey.


Congratulations! You have successfully installed and configured Redis on your Amazon Linux instance. Redis is now ready to be used as a cache, database, or message broker in your applications. Feel free to explore the various features and functionalities that Redis has to offer.
